我使用了来自 JClouds ( http://www.jclouds.org/documentation/quickstart/rackspace/ ) 的 Rackspace 示例代码，如果我使用我的 Rackspace 美国帐户。一切正常。
但是，如果我使用 Rackspace UK 帐户并想创建/启动服务器（访问数据和 API 是正确的），它就不起作用。Rackspace US 中的相同代码运行良好。
我不知道为什么？标头有效，我可以获取所有图像、服务器，并且可以删除服务器。但是启动一个新服务器是不可能的...... JClouds 重试 5 次以创建/启动一个没有成功的服务器，然后我得到了这个 Stacktrace；

编辑 21.08.2012
今天，我也尝试了 jclouds 版本 1.5.0-beta.10，但它不起作用。我有以下代码
final ComputeServiceContext context = new ComputeServiceContextFactory().createContext("cloudservers-uk", "user", "API", ImmutableSet.of(new SshjSshClientModule(), new SLF4JLoggingModule()));
getClient(context).createServer("SERVER_NAME", IMAGE_ID, FLAVOUR_ID);
context.close();
private CloudServersClient getClient(final ComputeServiceContext context)
{
return CloudServersClient.class.cast(context.getProviderSpecificContext().getApi());
}
以及以下依赖项
<dependency>
<groupId>org.jclouds</groupId>
<artifactId>jclouds-compute</artifactId>
<version>1.5.0-beta.10</version>
</dependency>
<dependency>
<groupId>org.jclouds</groupId>

问题出在哪里？谢谢你的帮助
